Clear the old icon in the Vista notification area

        Everyone knows that Windows systems can automatically hide inactive icons in the notification area, which is a very useful feature. However, over time, there are more and more icons in the notification area, some are icons long ago, and even the software has been uninstalled, so we figured out how to clean him up.
The increase in icons has caused bloat, and now teaches you an easy way to clean up the icons in the notification area. It's important to note that following this method will clear any settings you have made to the icon.
Right-click on the toolbar, select "Properties", then select the "Notification Area" tab, check "Hide Inactive Icons" and click "Custom".

When I see these icons on the list, some software has already been uninstalled by me, but the icons have survived.
Press "Win+R", enter "regedit" to open the registry editor, and then open the following key values:
HKEY_CURRENT_USER\\Software\\Classes\\Local Settings\\Software\\Microsoft\\Windows\\CurrentVersion\\TrayNotify< Br> You can see two files: IconStreams and PastIconsStream, and delete them.

Then call up the task manager to terminate the process "explorer.exe", then click "File - New Task" in the task manager, enter "explorer", press Enter to restart the system process. Now look at the icon in the notification area. Haha, the expired icon has been successfully cleaned up and the interface has become very refreshing.
